Background and Objectives: Various studies have shown that sex steroids affect cancer cells at cellular and molecular level. In this study, the anti-proliferation effects of testosterone, was investigated on gastric cancer cell line (AGS) and activity level of caspase-3, -8 and -9, was evaluated. Methods: In this laboratory experimental study, AGS cell line, were randomly divided into contro...
درمان سرطان به وسیله گیاهان دارویی، از دیرباز مورد توجه محققان بوده است. دراین میان، برخی گونه‌های گیاهی دارای موادی هستند که از طریق آپوپتوز و یا نکروز، موجب مهار یا از بین بردن سلول‌های سرطانی می‌گردند. خانواده نعناعیان و کاسنیان از جمله گیاهان دارویی هستند که دارای اثرات بیولوژیکی بسیار می‌باشند. هدف ازاین مطالعه بررسی اثرسمیت عصاره‌های گیاهان پونه و درمنه بر روی رده‌ی سلولی سرطانی معده (AGS...
Activators of G protein signaling (AGS), initially discovered in the search for receptor-independent activators of G protein signaling, define a broad panel of biologic regulators that influence signal transfer from receptor to G-protein, guanine nucleotide binding and hydrolysis, G protein subunit interactions, and/or serve as alternative binding partners for Gα and Gβγ independently of the cl...
BACKGROUND & OBJECTIVE Sodium butyrate (NaBT) can inhibit proliferation and induce differentiation of various tumor cells. This study was to investigate effects of NaBT on the proliferation and differentiation of human gastric carcinoma cell line AGS and explore the possible mechanism. METHODS AGS cells were treated with 0, 1.0, 2.0 and 4.0 mmol/L of NaBT. Cell proliferation was detected by M...
To determine a suitable condition for in vitro infection model of Cryptosporidium parvum, four different cell lines, AGS, MDCK, HCT-8 and Caco-2, were used as host cell lines which were cultured at various concentrations of added supplements. These supplement include fetal bovine serum (FBS), sodium choleate, ascorbic acid, folic acid, calcium pantothenate, para-aminobenzoic acid and pyruvate a...
We have reported that the ambient gyrus is the site with the greatest accumulation of argyrophilic grains (AGs) and that the degeneration of the ambient gyrus is responsible for dementia with grains. Here we analyzed 1,405 serial autopsy cases from 2 hospitals and detected AGs only in cases older than 56 years of age. The distribution of AGs followed a stereotypic regional pattern. Thus, we pro...
BACKGROUND We evaluated AGS-1C4D4, a fully human monoclonal antibody to prostate stem cell antigen (PSCA), with gemcitabine in a randomized, phase II study of metastatic pancreatic cancer. PATIENTS AND METHODS Patients with Eastern Cooperative Oncology Group (ECOG) performance status 0/1 and previously untreated, metastatic pancreatic adenocarcinoma were randomly assigned 1:2 to gemcitabine (...
We assessed the usefulness and reliability of computed tomography (CT scan) in evaluating adrenal hyperplasia in 38 patients, including 14 with Cushing's disease, 17 with idiopathic hyperaldosteronism (IHA), and 7 with the adrenogenital syndrome (AGS). Eighty-two normal subjects were also examined. We analyzed the shape of the adrenal gland and quantitated its thickness, width and length. Visua...
We have analyzed the self-reactive repertoires of IgM and IgG Abs in the serum of 19 patients with hyper-IgM syndrome (HIM) by means of a quantitative immunoblotting technique that allows for a quantitative comparison of Ab repertoires in health and disease by multiparametric statistical analysis. Normal tissue extracts of liver, lung, stomach, and kidney were used as sources of self Ags. Extra...
BACKGROUND AND PURPOSE Hetereothermic mammals tolerate hypoxia during euthermy and torpor, and evidence suggests this tolerance may extend beyond hypoxia to cerebral ischemia. During hibernation, CA1 hippocampal neurons endure extreme fluctuations in cerebral blood flow during transitions into and out of torpor as well as reductions in cerebral blood flow during torpor. In vitro studies likewis...
